Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520916, here are decompositions:

3 + 520913 = 520916
79 + 520837 = 520916
103 + 520813 = 520916
157 + 520759 = 520916
199 + 520717 = 520916
283 + 520633 = 520916
307 + 520609 = 520916
349 + 520567 = 520916

Showing the first eight; more decompositions exist.
